O’Brien is the First Female to Land the Trick at X Games in Aspen

Despite not landing on the podium, Spencer O’Brien still made history by stomping a huge backside 900 in slopestyle finals at Winter X Games 15 in Aspen, Colorado. This was the only  900 stomped by a lady in today’s slope finals.  O’Brien put down the trick on the last jump during her second run in finals on Sunday. She had planned to spin 720, but added  the last rotation and stomped her way to a new record in Aspen. Cheryl Maas was the first lady to land a backside 9  in competition at Euro X Games in 2012, and O’Brien makes history for stomping this one today.
